Kingspan OPTIM-R E Inverted Roofing System

The Kingspan OPTIM-R E Inverted Roofing System is perfect for projects that require the lowest U-value or the thinnest roof build-up. It is ideal for where there is little space for installing new roof insulation. Kingspan OPTIM-R E Inverted Roofing System is encapsulated in a coating for increased robustness and easier handling on-site. The vacuum insulation panels are accompanied by rigid extruded polystyrene insulation infill panels which can be cut to fit around problem areas such as roof lights or ventilator kerbs.

Product Highlights

• Next generation insulation with a superior level of thermal efficiency
• Ideal for constructions where a lack of construction depth or space is an issue
• Protective coating for increased robustness and easier handling
• Compatible with green roof systems

Optimum performance insulation for protected membrane flat roofs.

Kingspan OPTIM-R E Inverted Roofing System panels are rigid vacuum insulation panels with a microporous core which is evacuated, encased and sealed in a thin, gas-tight envelope. Kingspan OPTIM-R E Inverted Roofing System panels are encapsulated in a coating for increased robustness and easier handling on-site.

The vacuum insulation panels are accompanied by rigid extruded polystyrene insulation strips. They can be used where the remaining dimension to infill is below 300 mm or can be cut to fit around problem areas such as roof lights, ventilator kerbs or drainage gutters. 

Kingspan OPTIM-R E Inverted Roofing System panels achieve a thermal conductivity of 0.008 W/mK for panel sizes:

• 600 x 400 mm
• 600 x 600 mm
• 1200 x 400 mm
• 1200 x 600 mm

Kingspan OPTIM-R E Inverted Roofing System panels achieve a thermal conductivity of 0.009 W/mK for panel size:

• 1200 x 300 mm

NB: For inverted roofing applications, a design value thermal conductivity should be used. See the product brochure for further details.
